Javascript 在谷歌地图内外拖放元素
我知道这里已经有答案了: , 但这并不是我所需要的 我有一个带有购物卡的“口袋妖怪商店”网站 当用户在那里签出订单时, 我想让他们把项目拖入谷歌地图,然后弹出放置位置 我还有一个问题: 每一件物品都需要保存在object中,并注明物品的详细信息和放置位置,地图上的每一件物品都应该是返回购物卡的选项。 有可能吗?这是一个好的开始。 在地图上拖入拖出效果很好 添加API密钥Javascript 在谷歌地图内外拖放元素,javascript,jquery,google-maps,google-api,draggable,Javascript,Jquery,Google Maps,Google Api,Draggable,我知道这里已经有答案了: , 但这并不是我所需要的 我有一个带有购物卡的“口袋妖怪商店”网站 当用户在那里签出订单时, 我想让他们把项目拖入谷歌地图,然后弹出放置位置 我还有一个问题: 每一件物品都需要保存在object中,并注明物品的详细信息和放置位置,地图上的每一件物品都应该是返回购物卡的选项。 有可能吗?这是一个好的开始。 在地图上拖入拖出效果很好 添加API密钥 <style> html, body { width: 100%; height: 1
